A further -object is to provide improved means for securing the rave to the bench of the sled without the aid of screws, bolts, or rivets.

These and other objects not hereinbefore mentioned are accomplished by the construction illustrated in the accompanying drawings, wherein like letters of reference indicate corresponding parts in the several views, and in which- Figure l is a perspective view of my improved sled. Fig. 2 is a perspective view of the upper portion of the knees, socket, and a portion of the rave. Fig. 3 is a section on the line 3 3, Fig. l, parts being in section and showing the boss in dotted lines.

In the drawings, A designates the runners,-l

secured to the knees by means of a rivet E".

The bottolnportion of the socket is provided with an inwardly-extending portion F, which is provided with an aperture F'. On top of the socket is a `boss G and the tongues H. The lraves are provided with apertures B.

InV assembling theparts the sockets are secured to the upper ends of the knees, as before described, the raves are placed on top of the sockets, so that the boss on each socket will tit into the aperture in the raves, and the tongues are then clamped down over the raves. By this construction the raves are secured -to the sockets and' knees without the aid of screws, bolts, or rivets and at the same time are held rmly in position and are prevented from slipping longitudinally by means of the boss fitting into the aperture in the rave. The v'sockets are made of malleable iron, so that the tongues can be cold clamped down over the raves. This feature of the invention I regard as very important, for the reason that there are no screws, bolts, or rivetsZto work out of place, the appearance of the coupling is enhanced,and the cost of manufacture is greatly reduced. The sockets aremade of a single casting and being made of malleable iron are of sufficient strength to withstand all strain imposed upon them. The seat-board is detachably secured to the inwardly-extending portion F of the socket `by means of screws L passing through the aperture into the bottom of the cross-pieces after the protruding ends of the same 'have been inserted into the sockets.

To knock down the sled, it is only neces- Isary to remove the screws L from the seatboard, leaving the rave and its corresponding ruimer secured together by means of the kneesand sockets. The lip E is provided with the rib eto prevent the socket from turning between the upper ends ofthe knees, and 'thef rib is provided with the strengthening-web e'.

vI am aware that many minor changes can be made in the construction and arrangement of parts without in the least departing from the nature and principles of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a knookdown sled, the combination with board, and means for detaohably securing the runners and knees, of a socket secured the seat-board to the sockets. ro to the upper end of each knee, provided with Signed at Wabash, Indiana, this 12th day a boss and a pair of tongues, a rave provided of February, 1903.
